ok, you mean you imported table from a CSV file into TablePress, and then deleted that table in TablePress again?
Then, I'm really sorry. That process is not revertable. Deleted tables can not be restored, as they are deleted directly from the database.

So, unless you have a backup of the database, or of the CSV file, the table is lost :-(
One idea though: Depending on how much time passed between importing the file, and deleting the table, you might be lucky, as the Google cache or the Internet Wayback machine (http://archive.org/web/web.php) might have a copy in their cache.
